Clean Room Work Platforms

Platforms have a smooth finish and seamless welds, so there are no cracks or crevices that can harbor dust, dirt, and bacteria.

Note: The number of steps listed includes the platform.

316 Stainless Steel—They are 316 stainless steel to withstand repeated washdowns.

Perforated—Platform is perforated to provide slip resistance.

Perforated Step—Steps are perforated to provide slip resistance.

Four Swivel Casters—Easily move the platform with the four swivel casters.

Spring-Loaded Casters—They’re spring loaded to stay stationary while in use—when you step on, the casters retract; when you step off, the casters roll again.

Fed. Std. Class 100 and ISO Class 5—Access elevated areas with these platforms that meet Fed. Std. Class 100 and ISO Class 5 clean room requirements.

Fixed Work Platforms


Style 1	Style 2	Style 3

Style 4	Style 6

Install these platforms for easy access to elevated areas. They’re large enough to provide plenty of space for working. Platform and steps are serrated for maximum slip resistance and to allow dirt and debris to fall through. Without work boots, standing on them for extended periods may be uncomfortable.

Also Available: Other platform sizes. Please select 8031T999 and specify style number, platform size, and platform height.

Style 1

Style 1 allows you to lower the platform up to 3" by sliding the U-bolts. They don’t have handrails, so you can work freely in any direction.

Number of Steps—The number of steps listed includes the platform.

Specifications Met—Work platforms meet OSHA and Cal/OSHA dimensional and construction standards. Check local, state, and federal codes, including OSHA, for safe set up and operating practices.

Low-Height Crossover Stairs

2 Steps

Take the safest, shortest route over pipes and other obstacles near the ground. For stability, bolt these stairs to your floor.

Powder-Coated Steel—Powder-coated steel stairs are both rust resistant and durable enough to withstand heavy use. They’re yellow, so they are easy to see and reduce tripping risks.

Aluminum—Aluminum stairs are more corrosion resistant than steel stairs. They’re a good choice for damp areas, including outdoors.

Serrated Step—The serrated steps and platform prevent slipping and allow liquids and debris to pass through.

Specifications Met—All stairs meet OSHA and Cal/OSHA dimensional and construction standards. Check local, state, and federal codes, including OSHA, for safe set up and operating practices.

Build-Your-Own Fixed Work Platforms

Shown Assembled

Configure a work platform to fit your application.

First, determine how high your work platform needs to be and choose the stairs that accommodate that height. Then, choose a platform section based on the desired length. Next, choose platform supports that correspond to the height of your stairs—each end of the platform must be supported by a platform support. Finally, choose handrails for the stairs and platform. Assembled work platforms should be secured to a supporting surface (mounting hardware not included).

Stairs

Aluminum—Made of aluminum, these platforms are lightweight and corrosion resistant.

Serrated Step—Steps are serrated for maximum slip resistance.

Specifications Met—Work platforms meet OSHA dimensional standards. Users are responsible for checking local, state, and federal codes, including OSHA, for safe installation and operating practices. Work platforms also meet CAL-OSHA standards, which is required for use in California.

Rolling Work Platforms

Equipped with four casters, these platforms are easy to move between work areas. When you stand on these platforms, the spring-loaded casters automatically retract for a stable surface.

Style 3

Style 3 have a handrail on only one side for unrestricted access to a conveyor or machinery.

Aluminum—Aluminum platforms are lighter weight than steel platforms and resist corrosion.

Serrated Step—Serrated treads give you maximum slip resistance and allow liquids and debris to pass through.

Specifications Met—Work platforms meet OSHA and Cal/OSHA dimensional and construction standards. Check local, state, and federal codes, including OSHA, for safe set up and operating practices.
